Answer: Using the proportion beteween the sides of the similar triangles, the distance between the endpoints of the beams P and Q is 3.2 inches.
Option a. 3.2 inches
Solution
PR=3.7 inches; CR=5.6 inches; AC=4.9 inches
As the two triangles QRP and ARC are similar, their sides must be proportionals, then:
PQ/AC=PR/CR=QR/AR
Replacing the given values in the proportion above:
PQ/(4.9 inches)=(3.7 inches)/(5.6 inches)=QR/AR
PQ/(4.9 inches)=3.7/5.6
Solving for PQ: Multiplying both sides of the equation by 4.9 inches:
(4.9 inches)[PQ/(4.9 inches)]=(4.9 inches)(3.7/5.6)
PQ=(4.9)(3.7)/5.6 inches
PQ=18.13/5.6 inches
PQ=3.2375 inches
Rounding to one decimal place:
PQ=3.2 inches
True.

Answer:
0.67 feet
Step-by-step explanation:
This question can be interpreted as find the 11th term of a geometry progression where a = 6.25 and r = 80%
So, we have:
In this case:
So, we have:
Hence, the height of rebound at the 11th time is approximately 0.67
Answer:
30,000 mg
Step-by-step explanation:
In this case what we should do multiply the daily quantity by the number of days, that is:
They tell us that the daily amount is 500 milligrams, that is, 500 mg / day.
Now, the total time they tell us is 60 days, so we have:
500 mg / day * 60 day = 30,000 mg
That is, a total of 30,000 milligrams of chlorine in the 60 days.
